Comparison of in vitro, in vivo, and in silico bioavailability results of different prednisone tablet formulations to assess the feasibility of possible biowaiver
The immediate-release solid oral products containing very soluble and permeable drugs are candidates for the biowaiver process.
Physiologically Based Pharmacokinetic/Pharmacodynamic Modeling to Evaluate the Absorption of Midazolam Rectal Gel
We aimed to 1) develop physiologically based pharmacokinetic/pharmacodynamic (PBPK/PD) models of a novel midazolam rectal gel in healthy adults, 2) assess the contribution of different physiologically relevant...
Integration of Clinical and Scientific Principles in the Teaching of Drug-Drug Interactions
Evaluation of drug-drug interactions (DDIs) is an integral part of pharmacy practice worldwide.
Current Regulatory Requirements for Biosimilars in Six Member Countries of BRICS-TM: Challenges and Opportunities
The aim of the study was to identify, interpret, and compare the current perspectives of regulatory agencies in six member countries of BRICS-TM (Brazil, Russia, India, China, South Africa, Turkey, and Mexico) on the different criteria used for biosimilar development and marketing authorisation process.

Physiologically Based Pharmacokinetic Modelling of Inhaled Nemiralisib: Mechanistic Components for Pulmonary Absorption, Systemic Distribution, and Oral Absorption
Physiologically based pharmacokinetic (PBPK) modelling has evolved to accommodate different routes of drug administration and enables prediction of drug concentrations in tissues as well as plasma.
Development of PBPK model for intra-articular injection in human: methotrexate solution and rheumatoid arthritis case study
A physiologically based model describing the dissolution, diffusion, and transfer of drug from the intra-articular (IA) space to the plasma, was developed for GastroPlus v9.8.
Current computer-aided drug design methodologies in discovery of novel drug candidates for neuropsychiatric and inflammatory diseases
Drug discovery and development is a very challenging, expensive and time-consuming process.
The emerging role of physiologically-based pharmacokinetic/biopharmaceutics modeling in formulation development
Computer-based (in silico) modeling & simulation tools have been embraced in different fields of pharmaceutics for a variety of applications.
Pharmacokinetics of tulathromycin in pregnant ewes (Ovis aries) challenged with Campylobacter jejuni
The purpose of this study was to evaluate the pharmacokinetics of tulathromycin in the plasma and maternal and fetal tissues of pregnant ewes when administered within 24 hours of a...
Improving Dissolution Behavior and Oral Absorption of Drugs with pH-Dependent Solubility Using pH Modifiers: A Physiologically Realistic Mass Transport Analysis
Orally dosed drugs must dissolve in the gastrointestinal (GI) tract before being absorbed through the epithelial cell membrane.
PBPK Modeling as a Tool for Predicting and Understanding Intestinal Metabolism of Uridine 5′-Diphospho-Glucuronosyltransferase Substrates
Uridine 5′-diphospho-glucuronosyltransferases (UGTs) are expressed in the small intestines, but prediction of first-pass extraction from the related metabolism is not well studied.
Quantitative Systems Toxicology Modeling Predicts that Reduced Biliary Efflux Contributes to Tolvaptan Hepatotoxicity
Patients with autosomal dominant polycystic kidney disease (ADPKD) exhibit enhanced susceptibility to tolvaptan hepatotoxicity relative to other patient populations.
Computational pharmaceutics – A new paradigm of drug delivery
In recent decades pharmaceutics and drug delivery have become increasingly critical in the pharmaceutical industry due to longer time, higher cost, and less productivity of new molecular entities (NMEs).
